Muscle Spasms?!

I understand it's "too early" to feel the baby move between weeks 14 and 15, but I could swear when I'm laying very still that I feel small movements. They feel like what I remember of baby movements, but part of me wonders if they could be muscle spasm since it's so early... I'm going to give myself another couple weeks to figure it out, but how fun would it be to look back and realize I was feeling the baby at 14 weeks!
